Unreasonable optimization solution

Recommended Posts

Hello,

I run the optimization without errors. However when I check the results in the iso mode, the final step shows an model without elements already at an iso-value of 0.02 (only the non-design elements left). What am I doing wrong? The hist.mvw and the .out files attached belong to the mvw and hm files (when saving I only changed the version from 2 to 3).

 

Could anybody please help me?

Cheers

Daniel

Hi,

 

Mass and volume fraction is not a good combination for a design suggestion. Please use volume fraction with compliance as objective to start with.
